  • Process for large area deposition of diamond-like carbon films
    Patent number: 6090456
    Abstract: A new method for ion beam deposition of diamond-like carbon coatings onto a variety of substrates is described. A high power, radio frequency excited-inductively coupled ion gun directs a beam of carbon and hydrogen ions at a substrate inside an ultra vacuum deposition chamber. A four axis scanner is used for coating large and nonplaner substrates. A quadrupole mass spectrometer is mounted inside the deposition chamber for real time monitoring of ion composition. The disclosed method is particularly effective for coating zinc sulfide and zinc selenide infrared windows.
